The fundamental ideas of a movement image movie digicam ought to be effectively understood by most readers — in any case, it’s been effectively over 100 years for the reason that Lumière brothers wowed nineteenth century Paris with their first movies. However making one your self is one other matter totally, as they’re surprisingly advanced and high-precision units. This hasn’t stopped [Henry Kidman] from giving it a go although, and what makes his digicam extra outstanding is that it’s 3D printed.
The issue going through a 16mm film digicam designer lies in exactly advancing the movie by one body on the appropriate charge whereas filming, one thing carried out previously with a small steel claw that grabs every successive sprocket. His design eschews that for a sprocket pushed by a stepper motor from an Arduino. His rotary shutter is pushed by one other stepper motor, and he has the idea of an excellent digicam.
The checks present promise, however he encounters a stability drawback, as a result of because it seems, it’s tough to print a 16mm sprocket in plastic with out it warping. He solves this by aligning frames in post-processing. After fixing a spread of small issues although, he has a digicam that delivers an excellent image high quality, and that makes us envious.
Sadly, these of us who ply our film-hacking craft in 8mm don’t have the posh of sufficient house for a sprocket to switch the claw.
